Just for fun, and to plan for Farb's course next year, I came up with the
following calculations for our dive on the Titanic.

For safety concerns, we've decided to dive Trimix.

Here's my figures:

Bottom Depth:   13,627 FSW

Total Atmospheres:  414.94

Absolute Pressure at Depth:  6,099.61 psi

Maximum ppO2 you want at Depth:  1.24 (for safety, of course)

END  (Maximum Narcosis Depth you will tolerate)  100 FSW

% of N2 for END:  1%

Pressure Fill Calculation:

1)  Add 7 psi of O2 to your Cylinder

2)  Add Heliun to 2,976.92 psi in your cylinder

3)  Add Air to 3,000 psi in your cylinder.

At depth, you will encounter a Vacuum of 3,099 psi differential between
ambient pressure and the inside of your tank, which means a 17 cu. ft.
diluent sphere will suck your entire body and Mark 16 rebreather into it,
along with a fair amount of Titanic Artifacts.  Oh, it'll also wrinkle that
new O'Neill wetsuit you bought just for the occasion...

I can hardly wait...
